A Molecular Antiferromagnet TMTSF-FeCl_4
A semiconducting organic radical cation salt with a magnetic anion, TMTSF·FeCl<SUB>4</SUB> (ρ<SUB>rt</SUB> = 40 Ωcm), was prepared. The crystal undergoes an antiferromagnetic ordering below <I>T<SUB>N</SUB></I> = 4 K with the easy axis perpendicular to the TMTSF stacking direction. X-ray crystallographic analysis reveals that Cl atoms of the anions closely contact with Se atoms of the donor molecules and suggests that the spin ordering is mediated by magnetic interaction between donors and anions.
